Research On Civil Airport Clearance Range Optimization Considering Flight Procedure

AOFA(Aerodrome Obstacle Free Airspace) is critical to the flight safety and flight procedures implementation of civil aerodromes. Along with the transition of the aircraft navigation equipment as well as the rapid development of urban construction and the increasing number and scale of civil aerodromes in our country, the situation of AOFA is becoming more and more serious and many new problems have emerged.The thesis mainly aimed at the clearance management area of civil airport which implements traditional flight procedure and PBN procedure and gave a systematic research. First of all, the AOFA standards of Annex 14 of the International Civil Aviation Convention are compared and analized systematically with the Federal Aviation Regulations Part 77, United States Standard for Terminal Instrument Procedures and International Civil Aviation Organization's Procedures for Air Navigation Services: Aircraft Operations. And gives the scope of airport clearance area optimization method based on AOFA standards.Secondly, it compared traditional with PBN navigation equipment, gave the horizontal scope of airport clearance area optimization method based on PBN procedure. At last, it adjusted the standard parameter in the obstacle CRM(Collision Risk Model) according to the PBN procedure and put forward the vertical scope of airport clearance area optimization method based on PBN procedure, and an obstacle evaluation methods of airport which implements PBN procedure is established. The above research results formed in view of the clearance area optimization methods of airport which implements traditional flight procedure and PBN. And it can provide technical support and reference for our country's civil airport clearance management in the current and future.
